After less than three years at the helm of The Centers, Dr. Donald Baracskay has resigned his post as CEO of the Ocala-based mental health and substance abuse treatment facility. The move ratcheted up ongoing merger talks between The Centers and Daytona Beach-based SMA Healthcare. After Baracskay's decision to resign, the facility entered into a management agreement with SMA on Sept. 1 while the two entities seriously explore a merger.
